Quality assurance sampling techniques with small samples offer a method of monitoring performance of health services in small health areas, and of identifying areas with poor performance in which remedial actions need to be targetted. Lot Quality Assurance Sampling methods were used to assess the coverage resulting from three immunization campaigns in rural and urban areas in the mountains of Peru. Application of these methods in 12 health areas with populations of 538 to 15 780 by Ministry of Health personnel proved feasible and could be used to identify areas with poorer vaccination coverage. Further discussion about possible reasons for poor coverage led to corrective actions in these health areas and an improvement in overall coverage from 78% to 88% in a three-month period. These quality assurance methods are a useful supervisory tool to improve health programme performance.
小样本质量保证抽样技术提供了一种监测小健康区域卫生服务绩效的方法，以及识别绩效不佳区域以便采取补救行动的方法。采用批质量保证抽样方法评估了秘鲁山区城乡三次免疫活动的覆盖率。卫生部工作人员在12个人口从538至15780的健康区域应用这些方法，证明是可行的，可用于识别疫苗接种覆盖率较低的区域。对覆盖率低的可能原因进行的进一步讨论，促使在这些健康区域采取了纠正措施，并在三个月内将总体覆盖率从78%提高到了88%。这些质量保证方法是提高卫生项目绩效的有用监督工具。
